SPECIFICATION forming part of Letters Patent No. 435,364, dated August 26, 1890. Application filed May 2, 1890- Serial No. 350,263. (No model.)

To all whom it may concern.-

Be it known that I, LEWIS MILLER, of Mexico, in the county of Oswego, in the State of New York, have invented new and useful Improvements in Carriage-Poles, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of carriage-poles whichhave their shackle-i rons adjustable, so as to adapt the pole to be connected to different carriages having the pole- .ner sides,

shackles different distances apart.

The invention consists in an improved constru ction and combination of parts which permit the aforesaid adjustment to be effected in a convenient and perfect manner, and at the same time imparts superior stability to the attaching end of the pole, all as hereinafter more fully described, and specifically set forth in the claim.

In the accompanying drawings, Figure l is a plan view of the attaching end of a pole embodying my improvements. Fig. 2 is an enlarged plan view of one side of the pole attachment. Fig. 3 is a further enlarged transverse section on line a" 00, Fig. 2. Fig. 4 is a side view of the pole attachment. Fig. 5 is a detached side View of one of the attachingplates, and Fig. 6 is a detached side view of one of the shackle-irons of the pole.

' Similar letters of reference indicate corresponding parts.

P represents the carriage-pole, and C the curved wooden cross-bar, which is rigidly attached to the-pole in any suitable and wellknown manner. The end portions of said cross-bar are formed with straight inner faces disposed at corresponding angles to the pole and are provided either with a plurality of bolt-holes or with longitudinal slots a. To the said straight inner sides of the end portions of the cross-bar C are rigidly secured by bolts or rivets b 1) straight elongated metal plates 0 0, provided with bolt-holes or longitudinal slots 01 (1, corresponding to those of the crossbar. Said plates I preferably provide with longitudinal ribs e e on the edges of their inso as to form in said plates straight longitudinal channels e, as shown in Figs. 3 and 5 of the drawings.

D D represent the shackle-irons, by which the pole is connected to the usual shackles attached to the carriage. Each of these shackle-irons I form with a straight shank D, of rectangular shape in cross-section, and of a width to fit snugly in the channel a of one of the plates 0, into which it is inserted, as shown in Fig. 3 of the drawings. Said shank is provided with perforations or bolt-holes f f, as shown in Fig. 6 of the drawings, for the purpose hereinafter explained.

To reduce the bulk-yappearance of the crossbar C, I form the exterior of the two end portions thereof straight and tapering to corresponding angles to the pole. To these straight outer faces of the end portions of the crossbar I rigidly attach the pole-braces B B, the rear end port-ions of which are formed straight and flat on their inner sides, by which they lie closely against the aforesaid outer faces of the cross-bar, and are fastened thereto by the bolts or rivets which secure the plates 0 c to the cross-bar, as hereinbefore stated. The outer faces of the aforesaid portions of the pole-braces are each formed with steps 72. h reverse to the taper of the end portion of the cross-bar C or parallel with the channel e of the plate 0, to afford square bearings for the heads of the bolts Z l, as shown in Figs. 1 and 2 of the drawings. Said portions of the pole braces are also each provided with either a plurality of bolt-holes or with longitudinal slots '6 t, as shown in Fig. 4 of the drawings.

1 Z represent bolts which pass through the aforesaid bolt-holes and slots in the polebrace B, cross-bar C, plate 0, and shackle-iron shank D, and are provided with nuts on their protruding ends. By loosening the said nuts tne shackle-irons can be shifted longitudinally on the plates 0 o, as shown by dotted lines in Fig. 2 of the drawings, and thus the shackle-eyes of said irons can be made to stand at different distances apart to correspond to the distance between the shackles on the carriage, and in said adjusted position the shackle-irons D D are retained by tightening the nuts on the bolts Z Z. The ribs 6 e on the plates 0 c serve to eifectually prevent lateral displacement of the shackle-iron shanks D D.

Having described my invention, whatI claim ing on the inner secure by Letters Patwith the pole P, the crossbar 0, provided with slots a a, the plate c,1yside of the cross-bar and formed with the straight longitudinal ribs e in its inner side and provided with slots d d,

the brace 13, resting on the outer side of the cross-bar and formed with steps h h, parallel w th the channel a, and provided with slots L 1, bolts or rivets b b tying the aforesaid brace and plate to opposite sides of the cross-bar,

the shackle-iron shank D, formed straight and seated in the channel e, and provided with bolt-holes f f and bolts Z Z, passing through 15 the slots and bolt-holes of the brace, crossbar, plate, and shackle-iron shank, substantially as described and shown.

In testimony whereof I have hereunto signed my name this 29th day of April, 1890.
